al-Daraqutni

Ali ibn Umar al-Daraqutni al-Baghdadi (306–385 AH / 918–995 CE) was one of the greatest hadith critics of the fourth Islamic century, the author of the Sunan al-Daraqutni and numerous other works, and the undisputed master of hadith science in Baghdad during his lifetime. He was born in the Dar al-Qutn neighborhood of Baghdad, from which his name is derived, and spent his entire scholarly life in that city.

He studied under the major scholars of his generation including Ibn Abi Dawud, Abu al-Qasim al-Baghawi, and many others. He became so expert in hadith knowledge that contemporaries described him as unique in his generation. His ability to memorize and recall complete chains of transmission — with all their variations, errors, and points of contention — was considered supernatural by those who witnessed it.

His major work the Sunan is a collection focused specifically on hadith relevant to fiqh (Islamic law), organized by legal topic, with extensive notes on the reliability of narrators and the status of each tradition. It is particularly valued for the way it includes traditions not found in the six canonical collections and for its critical apparatus on chain variants.

He also composed al-Ilal al-Warida fi al-Ahadith, a multi-volume work on hidden defects in hadith chains, and wrote on the Quran, biographies of narrators, and other topics. His works are standard references in the hadith sciences. He died in Baghdad in 385 AH and is considered one of the last of the absolutely first-rank hadith masters before the tradition shifted from primary collection to commentary and codification.
